Powered by Harley-Davidson, the Serial 1 MOSH/CTY model is the ultimate urban playbike. This pedal-assist eBicycle is designed for trend-setting adults seeking a stylish and flexible way to move around their fast-paced urban environments. Fly faster and farther, solo or in a pack. It's quick, nimble, and an absolute ripper.

The lightweight, mid-mounted Brose S MAG motor features a brushless internal rotor and produces plenty of power assistance to provide a quick launch from a standing start and to give the rider the ability to conquer challenging hills. The Gates carbon-fiber belt drive is smooth, quiet, and maintenance-free. It requires none of the frequent lubrication or adjustment of a traditional chain-drive system. The MOSH/CTY uses a single-speed freewheel hub for the most direct connection between the rider and the road.

The MOSH/CTY is equipped with an integrated, 529Wh lithium-ion battery that can be quickly removed from the frame without tools. The battery locks into the frame for enhanced security. This battery delivers a real-world range of 35-105 miles, depending on ride-mode selection, terrain, and how much pedal input the rider supplies. It can be charged on the bike through a charging port conveniently located on the frame down tube, or easily removed for off-the-bike charging.

Front and rear hydraulic disc brakes utilize two-piston calipers and 203 x 1.8mm brake rotors designed to deliver confident braking performance in most riding conditions. This is essential for faster-moving eBicycles and all-weather commuting.

Wheels consist of 27.5 x 35mm alloy rims laced with stainless-steel spokes and fit with high-volume, 2.8" Schwalbe Super Moto-X tires. The result is a perfect combination of low rolling resistance, ample shock absorption, and responsive, predictable handling.

A bright LED headlamp mounted on the handlebar stem illuminates the path ahead and can make the rider more conspicuous after dark. Bright combination LED tail and brake lights integrated into the frame dropouts are designed to make the bike more visible from the rear. A distinctive LED front signature light illuminates whenever the eBicycle is powered up.

Eco Mode – A gentle amount of assistance in flat-and-favorable conditions.
Tour Mode – The optimal blend of assistance and battery economy under mixed riding conditions.
Sport Mode – Pronounced assistance away from corners or over rolling hills.
Boost Mode – For confronting a steep hill, a strong headwind, or any other condition requiring a sustained boost.

Frame geometry is optimized for each frame size to maintain a comfortable riding position and consistent handling across all rider sizes, regardless of rider height. Brake lines and electrical wiring are routed through the frame, promoting longer life and less maintenance through protection from the elements and clean, snag-free styling. Contemporary design touches like the integrated battery, the elevated chainstays, and the mass-centralized motor position all mark the beauty, craftsmanship and emotional connection inspired by Harley-Davidson.
